## To set the number of binary API trace records in the circular buffer, configure nitems

## nitems <nnn>
##
## To save the api message table decode tables, configure a filename. Results in /tmp/<filename>
## Very handy for understanding api message changes between versions, identifying missing

## In the VPP there is one main thread and optionally the user can create worker(s)
## The main thread and worker thread(s) can be pinned to CPU core(s) manually or automatically
## Manual pinning of thread(s) to CPU core(s)
## Set logical CPU core where main thread runs, if main core is not set
## VPP will use core 1 if available
# main-core 1
## Set logical CPU core(s) where worker threads are running
# corelist-workers 2-3,18-19
## Automatic pinning of thread(s) to CPU core(s)
## Sets number of CPU core(s) to be skipped (1 ... N-1)
## Skipped CPU core(s) are not used for pinning main thread and working thread(s).
## The main thread is automatically pinned to the first available CPU core and worker(s)
## are pinned to next free CPU core(s) after core assigned to main thread

## Specify a number of workers to be created
## Workers are pinned to N consecutive CPU cores while skipping "skip-cores" CPU core(s)
## and main thread's CPU core

## Set scheduling policy and priority of main and worker threads
## Scheduling policy options are: other (SCHED_OTHER), batch (SCHED_BATCH)
